Climbing rose plant named &#39;Kornagelio&#39;

ABSTRACT

A new and distinct variety of Climbing Rose Plant, herein referred to by its cultivar name, ‘KORnagelio’, is provided which forms in abundance on a substantially continuous basis attractive, double pink colored blossoms. The vegetation is vigorous and the growth habit is climbing. Attractive glossy, dark green foliage is formed. The resistance to disease is very good. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification: Latin name—Rosa hybrida. Common name—Climbing Rose Plant. Varietal Denomination—‘KORnagelio’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Climbing Rose Plant of the present invention was created by during May 2005 at Klein Offenseth-Sparrieshoop, Germany by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., seed parent) of the new variety was the ‘DELeri’ variety (non-patented in the United States). The male parent (i.e., pollen parent) was the (‘KORgosumu’x‘KORvanaber’) variety (non-patented in the United States).

The parentage can be summarized as follows:

‘DELerr’(‘KORgosumu’x‘KORvanaber’)

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Climbing Rose Plant of the present invention possesses the following combination of characteristics:

-   -   (a) abundantly and substantially continuously forms attractive,         double pink colored blossoms,     -   (b) exhibits a climbing growth habit,     -   (c) forms vigorous vegetation,     -   (d) forms attractive ornamental glossy, dark green foliage, and     -   (e) exhibits very good disease resistance.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the ‘DELeri’ variety (i.e., seed parent) displays smaller flower size with a lower petal count than that of the new variety. Additionally, the (‘KORgosumu’x‘KORvanaber’) variety (i.e., pollen parent) exhibits cream colored flower, whereas the new variety forms pink colored flowers with a higher petal count and has stronger vigor.

The new variety has been found to undergo asexual propagation in Klein Offenseth-Sparrieshoop, Germany by a number of routes such as budding. Asexual propagation techniques in Germany have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORnagelio’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately five years of age and was observed during July 2014 while budded on its own roots and growing outdoors at Sparrieshoop, Germany.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition). The terminology which precedes reference to the chart has been added to indicated the corresponding color in more common terms. The description is based on the observation of a three-year-old specimen of the new variety, observed during July, while growing in a three-gallon container on its own roots in Cochranville, Pa.
